Albano , here are your personalized Asterisk configuration settings. Print them out and keep them in a safe place, but do not share them with others. If testing or debugging with a softphone, FireFly (scroll down to third-party download link) works well for Windows although it is only optimized for the ILBC codec. iaxComm also works on Windows/Linux but some find it more complex. Neither is recommended nor supported by VoipJet.com, and does not help you with setting up Asterisk properly, so download and use at your own risk.

VoipJet account number (username/UserID): 93xx
Authorization code (password): 8905ffa6d357c3xx (You should see an MD5 string, if it is blank logout and login again and/or use a recent version of Internet Explorer browser)

Test Server: test.voipjet.com - no minimum balance to use, allows only one call at a time.
Production Server: east.voipjet.com - requires greater than 20 dollar balance to use. Beautiful Level3 bandwidth in 60 Hudson, NYC.
Second Production Server: nac.voipjet.com - requires greater than 20 dollar balance to use. CLOSED to new users. All users with id numbers greater than 27000 must request access to this server if they really want to use it.
West Coast Production Server: west.voipjet.com - requires greater than 20 dollar balance to use. Beautiful Level3 bandwidth in One Wilshire, LA.
Dialer and call-center Server: dialer.voipjet.com - requires greater than 20 dollar balance to use. Send all USA-destined dialer traffic here. Automatically bounces non-US traffic.
Dialer and call-center Server: dialer2.voipjet.com - requires greater than 20 dollar balance to use. Similar to dialer but on Level3 bandwidth. Ideally, balance your traffic between the dialer and dialer2 servers.

Try and enter the domain name in your iax.conf (e.g. test.voipjet.com) but if you are having DNS issues enter the IP address directly!

For Asterisk@Home AMP see this screenshot. For the regular Asterisk PBX setup, see below:

Asterisk PBX Step 1: Add the following lines to the end of iax.conf (found in /etc/asterisk)

; NANPA: North American Numbers dialed as 1 + area code
; For example, the New York Public Library is dialed as 12123400849
; 1 (North American call) 212 (New York area code) 3400849 (libary's phone number)
; WORLD: International Numbers dialed as 011 + country code + number
; For example, the Tate Modern Museum in London, U.K. is dialed as 011442078878000
; 011 (International call) 44 (U.K. country code) 2078878000 (museum's number)
; Finally, the number just before @voipjet in the Dial string is your VoipJet userid # ; and it needs to be there!

exten => _1NXXNXXXXXX,1,SetCallerID(4153574000); Set your CallerID as a ten digit number like this. See our FAQ
exten => _1NXXNXXXXXX,2,Dial,IAX2/93xx@voipjet/${EXTEN} ; VoipJet.com NANPA
exten => _011.,1,SetCallerID(4153574000); Set your CallerID as a ten digit number like this. See our FAQ.
exten => _011.,2,Dial,IAX2/93xx@voipjet/${EXTEN} ; VoipJet.com WORLD
;Do not change IAX2/93xx in the above two lines!

Step 3 (recommended): Set your codec to G.711 ulaw for optimal sound clarity and minimal transmission delay. In iax.conf (found in /etc/asterisk) locate the codec section and include the following only.
